Dicta singlespeed frihjul
Chrome finish - looks good on modern or oldschool bikes - very simlar in looks to the original (and best!) Chrome Suntour freewheels.
16 & 17T takes a regular 4 point frewheel removal tool (ie/ ACS). BTW you don't need a tool to fit it (it just screws on by hand and tightens the first time you pedal), just to remove it.
1/8 teeth - fits everything but the narrow 3/32 race chains.
